Hmm so you suggest i should update my firmware to the latest one? Well i'll give it a try and what do you mean by using the 3.71 MS drivers? I thought that when you update the firmware, it goes along with the MS drivers too? heh i guess i still got a lot to learn about the cfws.
EDIT: Well nevermind, i dunno what that 3.71 Ms driver meant but now i've updated the firmware, the cheat menu is popping up now on the UMD games
